An extension for his turret to mount on his back to give more arm space and give him the more G1 Cartoon look. And side holes for his 2 guns to store into as well. This one also has 2 height positions, so you can choose how the backpack sits.
Uses 5 mm pegs. It is 5mm long for both ends to plug in and inbetween 10mm space.
If you want a longer extension just contact me or you.
